What is Biodynamic Agriculture

Biodynamic agriculture is a method of organic farming that treats farms as unified and individual organisms, emphasizing balancing the holistic development and interrelationship of the soil, plants, animals as a self-nourishing system without external inputs insofar as this is possible given the loss of nutrients due to the export of food. As in other forms of organic agriculture, artificial fertilizers and toxic pesticides and herbicides are strictly avoided. There are independent certification agencies for biodynamic products, most of which are members of the international biodynamics standards group Demeter International.

Regarded by some as the first modern ecological farming system and one of the most sustainable, biodynamic farming has much in common with other organic approaches, such as emphasizing the use of manures and composts and excluding of the use of artificial chemicals on soil and plants. Methods unique to the biodynamic approach include the use of fermented herbal and mineral preparations as compost additives and field sprays and the use of an astronomical sowing and planting calendar. Biodynamics originated out of the work of Rudolf Steiner, the founder of anthroposophy.

The development of biodynamic agriculture began in 1924 with a series of eight lectures on agriculture given by Rudolf Steiner at Schloss Koberwitz in what was then Silesia, Germany, (now in Poland east of Wrocław). The course was held in response to a request by farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers. An agricultural research group was subsequently formed to test the effects of biodynamic methods on the life and health of soil, plants and animals.

Today biodynamics is practiced in more than 50 countries worldwide. Demeter International is the primary certification agency for farms and gardens using the methods.
